Fused hexacyclic tin compounds derived from 3-(3,5-di-t-butyl-2-hydroxy-phenylimino)-3H-phenoxazin-2-ol

The template synthesis of dimethyl (1) and diphenyl tin (2) compounds [N→Sn] 3-(2-oxo-phenylimino)-3Hphenoxazin-2-oxo-tin (1) is reported. They are fused delocalized planar hexacyclic systems bearing a pentacoordinated diorganyl tin and were identified by NMR, IR, TOF mass spectra and, for 1, by X-ray diffraction analysis.
